Please tell me how you can change the code in VanitySearch, instead of looking for an address, I need to replace it with a search
public key? That is, set the Gx point search function.

Let's say the public key is 03609747D18DB797783F8DA35BD9D95AAF717C99923D85CCF79C5396F8B897A960

Remove perfis 03

leave only Gx point and run

./VanitySearch -s "609747D18DB797783F8DA35BD9D95AAF717C99923D85CCF79C5396F8B897A960" -kp

I don't really know programming. I would be grateful for your answer!
